Yes, I have tried another power lead with no luck. I also tried the original power lead on another appliance and it worked okay.
More information which may or may not be relevant.
I hadn't used this printer for a couple of week or so. When I switched it on, the ON light came on and the OUT OF PAPER light also came on. I switched the printer OFF and filled it with paper. When I switched the printer ON again nothing happened. No lights.
